Information is currently gradually becoming “new oil” in terms of value. The only problem is that the volumes of data to be processed are growing by leaps and bounds. The sizes of files are sometimes larger than the hard drive, not to mention that RAM can’t cope, and interviewees receive increasingly scary tasks like comparing two petabyte files on the fly. But, fortunately for programmers, there is no need to make the machine choke on such amount of information, as iterators and generators can be used for threading, and there is also Python, a programming language which supports them perfectly. Would you like me to tell you about that?
Apache Tomcat is a server of web applications primarily used in commercial environment not only as an application platform, but also as a component of large projects related with providing of a web-interface. In corporate sector, security of information systems has the highest priority, while infrastructure stability ensures failure-free operation. Let us test a vaunted stability and security of UNIX daemons taking Tomcat as an example.
Since the beginning of dynamic Web development, а synchronization problem has emerged concerning a set of software programs, its versions and configurations in production and development environments. The developer of Vagrant has invented a new tool which is supposed to help solve the problem — Packer.
Linux supports a highly versatile set of administration tools. On the one hand, it is good — users have options. But, on the other hand, this very variety is not quite suitable for a corporate sector, as there are often tens and hundreds of computers to be managed. Recently, quite a number of tools have emerged to simplify this task, and we will discuss one of them.
Relatively recently, we saw the release of Red Hat Enterprise Linux 7, a distribution that is rightly considered to be the number one in the corporate sector. Without waiting for its clones, we decided to look at what is new in this giant of open source world which was able, at some point, to combine the seemingly incompatible – making money and using an open-source model.
Bug Bounty—vulnerability reward programs for vendors—become more and more widespread. And sometimes, vulnerabilities search detects some evidently insecure areas (e.g., self-XSS) the threat of which is hard to prove. But the larger (or even the smarter) is the vendor (e.g., Google), the more willing it is to discuss, to detect the indicated vulnerability and to reward if successful. This article is a collating of complex situations and the ways to prove a threat and to make the Internet more secure.
